Astoria Marine Construction Company

Site summary

The Astoria Marine Construction Company, or AMCCO, site is contaminated with hazardous chemicals from historical ship manufacturing and repair operations. Contamination is in soil on the property and in nearby riverbed sediment in the Lewis and Clark River near the mouth of the Columbia River.

In coordination with AMCCO, tribal governments, and a community advisory group, DEQ selected a remedy in 2017 to clean up contamination on the site and in the adjacent riverbed. AMCCO will implement the cleanup remedy with DEQ oversight.

Status of the cleanup

AMCCO completed all major remedy construction activities during the spring and summer of 2020. These included preparation activities such as demolition of select onsite buildings and structures followed by excavation of contaminated sediments in marine ways and upland soil hot spot removal for offsite landfill disposal. In the summer of 2021, AMCCO restored the levee and constructed a stormwater system. DEQ anticipates AMCCO will complete all elements of the remedy in summer 2022, which will focus on capping the upland area. 

Once cleanup work is complete, DEQ will issue a certification of completion documenting the terms of the 2018 settlement agreement between AMCCO and DEQ have been met. DEQ will conduct performance monitoring of the in-water remedy to confirm the cleanup's effectiveness.

Project updates will be posted here. More resources are provided below. If you have additional questions, you can reach out to the DEQ Project Manager, Erin McDonnell.
